AMD Hero Is Giving Return to Castle Wolfenstein a Path Tracing Update

A senior graphics R&D engineer at AMD, Dihara Wijetunga, posted on her Twitter page about a real-time version of Return to Castle Wolfenstein (RTCW) coming to PC, called Wolf PT.

Through his own passion and initiative, Wijetunga is bringing ray tracing technology to fans of the game and, as the name suggests, is using path tracing to lighten the load of the real-time lighting effect. Changes to the OG game will include improvements to lighting and shadows from the much-loved Nazi assassination, first-person shooter, although on a side-by-side comparison it looks like a little more than just that will be changing.

Keep in mind that these photos come from early stages of development, but there may actually be some brighter spaces emerging from the darkness of Castle Wolfenstein, thanks to the new techniques Wijetunga is utilizing.

Wolf PT will be based on open source iortcw engine (opens in new tab), although it comes with its own custom DX12 backend. meaning it goes use your CPUs integrated graphics (opens in new tab) to improve performance. “This is an RT with DXR hardware triangle, so it requires an acceleration framework,” says Wijetunga in the Twitter comments.

Later being previously reviewed by fans (opens in new tab), the originally Xbox exclusive game has finally arrived on Steam. In the process, it gained an expanded arsenal and weapon overhauls, better boss fights, and improved AI, among other things. Now the game will benefit from the joys of path tracing.

In the comments, Wijetunga notes that he doesn’t plan on using “RT for DoF or Motion Blur as the radius budget is so small for realtime”. Instead of using ray tracing for depth of field and motion blur effects, he plans to spend the small ray budget on “a clean image every frame and add in DoF and Motion Blur as a post-processing effect.”

He admits, however, that he is considering adding caustic (opens in new tab) as a ray tracing effect. This means that light shining through liquid and glass can end up looking really impressive.

Considering that this is a game that comes with some of the best flamethrowers found in games (opens in new tab), we are looking forward to the final product. For the moment, however, there is still some way to go.
